SPECIFICATION forming part of Letters Patent No. 399,696, dated March19, 1889.

Application led November 3, 1888. Serial No. 289,865. (No model.)

To all whom, it may concern.-

Be it known that I, ADoLrH RAssINIER, of Louisville, in the county ofJefferson and State of Kentucky, have invented a new and usefulImprovement in Nut Locks or Holders, which improvement is fully setforth in the following specification.

This invention relates to devices for holding or lockingI nuts, so as toprevent them from turning on their bolts and workin g loose.

The device is specially applicable to the bolts and nuts used forholding the tish plates or bars by which`rails are joined together, thenuts used for this purpose being particularly liable to become loosenedby the concussion caused by passing trains. The device, however, is notlimited to this use.

` The improved nut-holder consists of three parts: first, a bar or plateadapted to be placed against the iish-plate and having at each end anotch embracing each one of the bolts, the nuts being screwed down uponthis plate; second, a locking bar or plate with square notches in itsends, in which the nuts tit and which prevent their turning; and, third,a clamp which is slipped over the two plates and holds the parts firmlytogether.

The device can be quickly applied and taken oit, as desired.

In the accompanying drawings, Figure l is a perspective view of thenut-holder; Fig. 2, a cross-section; Fig. 3, a perspective view with theclamp removed, and Fig. 4 a detail view of the clamp.

A represents the rails, B the fish-plates, O the bolts, and D the nuts,all of the usual construction.

Plate E has a notch, e, at each end, and is of such length that when putin place the bolts O will pass through these notches. Nuts D are thenscrewed down tight upon these plates and turned to the positions shownin the drawings. Locking-plate E has square notches f in its ends, thesenotches being of the same size as nuts D, which iit therein when plate Fis put in position, as shown. It is evident that it is impossible forthe nuts to turn so long as plate E is in place. The latter is held inposition by a U-shaped clamp, G, which is slipped over the middleportion of platesE F. Said plates at this part are cut away, as shown inEig. 3, so that when clamp G is slipped over them ilush surfaces arepresented on all four sides, as shown in Eig. l. This construction alsoprevents clamp G from slipping.

I claixn- A nut locking or holding device comprising, in combination,the following elements: a plate having notches or apertures for thepassage of the bolts and adapted to be held by the nuts screwed uponsaid bolts, a second plate having angular notches for locking the nuts,and a U-shaped holding-clamp fitting over t-he two plates, substantiallyas described.

In testimony whereof I have signed this speciiication in the presence oftwo su bscrib'- ing witnesses.

ADOLPH RASSINIER.
